"...I'm not convinced anybody would actually want to self-insure here" Recognition of the possibility that self-insurance is an option?
As you have stated, it may not be an option; but......
If it were available, subject to 'section C of 4007', why would you not want to self-insure?
Recognition of creative editing (also known as LIEING) on your part. Let's look at the very first sentence I wrote in 94:
From my read of 4007 (post 82) I don't think it's available to the general public.
Gee since I quoted section C maybe you should read it. Having your certificate yanked on 5 days notice is pretty ugly. Also having only 30 days to payoff any settlement is pretty nasty. Of course the problem of having to own 25 vehicles (section A) is also rather daunting.
